Cardiovascular diseases are the most common cause of mortality and morbidity in adults worldwide.1 Coronary angiography (CAG) is the gold standard method for evaluating atherosclerotic coronary artery disease (CAD).2 It is conventionally performed via the trans-femoral (TF) route. Recently, however, the trans-radial (TR) route has become the preferred way.3 The TR route offers better procedure comfort, shorter hospitalization […]

Abstract

Overview

Background. The effect of ranolazine (RAN) on cardiac autonomic balance in congestive heart failure (CHF) was
studied.
Methods. Fifty-four CHF patients were randomized to (1) open-label RAN (RANCHF) added to usual therapy vs.
(2) usual therapy (NORANCHF). Parasympathetic and sympathetic (P&S) measurements were taken at baseline
and at 12 months.
Results. A total of 16/27 (59%) patients in both groups had initially abnormal P&S measures, including high
sympathovagal balance (SB), cardiovascular autonomic neuropathy (CAN) or both. High SB normalized in 10/12
(83%) RANCHF patients vs. 2/11 (18%) NORANCHF patients. SB became high in 5/11 (45%) NORANCHF vs. 1/11
(9%) RANCHF patients. CAN improved in 4/6 (67%) RANCHF patients vs. 5/7 (45%) NORANCHF patients. CAN
developed in 1/11 (9%) RANCHF vs. 4/11 (36%) NORANCHF patients. Since improved P&S in RANCHF patients
seemed independent of improved brain natriuretic peptide and impedance cardiography (BioZ) measurements,
5 day RAN was given to 30 subjects without CHF but with high SB or CAN. P&S improved in 90% of these subjects.
Conclusions. RAN improves unfavorable P&S activity in CHF possibly by a direct effect upon autonomic sodium
channels.
